One problem I have had with mutt and I don't see it fixed in the current issue relates to GPG support. It appears that when I send an encrypted e-mail, mutt does the obvious thing and saves the encrypted e-mail in my sent folder. But that's encrypted /to the receiver/, not to me. Hasn't this bothered enough people for mutt to fix it, so that GPG-encrypted e-mails are encrypted-to-self when copied to Sent?
